摘要
A novel method for fabricating sampled amplitude mask is presented I the feature of which is the varying sampling period and fixed sampling duty ratio. By using such an amplitude mask, sampled fiber gratings with different wavelength spacings of reflectivity peaks can be easily fabricated. So the novel method has the advantages of reduced fabrication cost and improved versatility of sampled grating. The possible disadvantages of the method are also discussed. Wavelength selectable fiber laser with vernier wavelength tuning mechanism is also demonstrated by the sampled fiber grating.
